Download or read book Distribution of Selected Trace Elements in Rocks written by Ronald J. Kley and published by . This book was released on 1968 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report discusses factors influencing trace element distribution in rocks, tabulates maximum and minimum concentrations of twenty-nine trace elements in various common rock types, and briefly describes the geochemical behavior of each of these elements. A procedure is outlined for predicting concentrations of these selected elements in various rock types. On the basis of this study it is concluded that: 1. Trace element concentration varies systematically according to the gross mineralogical composition of the host rock. 2. Mineralogical composition of the host rock is the primary determinant of trace element concentrations. 3. Knowledge of rock mineralogy as provided by conventional petrographic analyses serves as a basis for estimating trace element concentrations.

Download or read book The Nature of Magmatism in the Appalachian Orogen written by A. Krishna Sinha and published by Geological Society of America. This book was released on 1997-01-01 with total page 892 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thermal evolution of mountain belts is recorded inthe distribution, origin and ages of magnatism. In this volume, petrologic, isotopic and geochemical evidence is presented to highlight the contribution of igneous rocks to the evolution of the Appalachian Orogen in both Canada and the United States. These papers emphasize the use of modern geochemical and petrologic data to discriminate the sources yielding magmas, and thus the nature of the crust and mantle.

Download or read book Trace Elements in Igneous Petrology written by C.J. Allègre and published by Elsevier. This book was released on 2013-10-22 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trace Elements in Igneous Petrology, 5: Developments in Petrology: A Volume in Memory of Paul W. Gast focuses on the contributions and influence of Gast in petrology, including crystallization, magmatic processes, isotopic composition, and ocean ridge basalt chemistry. The selection first takes a look at quantitative models of trace element behavior in magmatic processes; application of trace elements to the petrogenesis of igneous rocks of granitic composition; and an assessment of local and regional isotopic equilibrium in the mantle. Discussions focus on evidence derived from time constraints, scale of isotopic disequilibrium, fractional crystallization, trace element modeling, geodynamics and tectonic setting, partition coefficients, quantitative models for trace elements, and parameter determination and inverse-problem solution. The publication then examines the isotopic composition of lead in oceanic basalt and its implication to mantle evolution; strontium isotopes in basalts from the Pacific Ocean basin; and trace elements in ocean ridge basalts. Concerns cover variations in ocean ridge basalt chemistry, trace elements in ocean ridge basalts, disequilibrium partial melting, seawater alteration, background for lead isotope tracer studies, and uranium, thorium, and lead concentrations in basalts. The book examines trace elements and anorthosite genesis, lead isotopes in Archaean plutonic rocks, early Archaean rocks and geochemical evolution of the earth's crust, and factors controlling the noble gas abundance patterns of deep-sea basalts. The selection is a valuable source of data for researchers interested in petrology.

Download or read book The Geology of the Carolinas written by J. Wright Horton and published by Univ. of Tennessee Press. This book was released on 1991 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: To celebrate its fiftieth anniversary, the Carolina Geological Society invited forty-three authors to contribute to the creation of The Geology of the Carolinas. The only comprehensive, modern treatment of the subject, the volume has been prepared for a diverse readership ranging from undergraduate students to specialists in the fields of geology and related earth sciences. Following the editors' general introduction are chapters on Precambrian and Paleozoic metamorphic and igneous rocks of the Appalachian Blue Ridge and Piedmont; rocks of early Mesozoic rift basins, formed just before the opening of the Atlantic Ocean; Cretaceous and Tertiary sedimentary deposits of the Atlantic Coastal Plain; Quaternary geology and geomorphology; Cenozoic tectonism, including evidence for the recurrence of large earthquakes near Charleston; and an overview of mineral resources in the Carolinas. The book includes an index of field guides produced by the society and a thorough bibliography. By introducing exciting new concepts and focusing on challenging problems on the frontiers of research, this authoritative book will stimulate research in the years to come. The Editors: J. Wright Horton, Jr., is a research geologist for the United States Geological Survey in Reston, Virginia. Victor A. Zullo is a professor of geology at the University of North Carolina at Wilmington.
